<h1>ov_pcm_seek_page</h1>
<p><i>declared in "vorbis/vorbisfile.h";</i></p>
<p>Seeks to the closest page preceding the specified location (in pcm samples) within the physical bitstream. This function only works for seekable streams.
<p>This function is faster than <a href="ov_pcm_seek.html">ov_pcm_seek</a> because the function can begin decoding at a page boundary rather than seeking through any remaining samples before the specified location. However, it is less accurate.
<p>This also updates everything needed within the
decoder, so you can immediately call <a href="ov_read.html">ov_read()</a> and get data from
the newly seeked to position.

<h3>Parameters</h3>
<dl>
<dt><i>vf</i></dt>
<dd>A pointer to the OggVorbis_File structure--this is used for ALL the externally visible libvorbisfile
functions.</dd>
<dt><i>pos</i></dt>
<dd>Position in pcm samples to seek to in the bitstream.</dd>
</dl>
<h3>Return Values</h3>
<blockquote>
<ul>
<li>0 for success</li>
<li>
nonzero indicates failure, described by several error codes:
<ul>
<li>OV_ENOSEEK - Bitstream is not seekable.
</li>
<li>OV_EINVAL - Invalid argument value; possibly called with an OggVorbis_File structure that isn't open.
</li>
<li>OV_EREAD - A read from media returned an error.
</li>
<li>OV_EFAULT - Internal logic fault; indicates a bug or heap/stack
corruption.
</li>
<li>OV_EBADLINK - Invalid stream section supplied to libvorbisfile, or the requested link is corrupt.
</li>
</ul></li>
</ul></blockquote>
